V TIME-CONTROLLED FURNACE-STARTER.

Application filed. February 9, 1917.

To all whom it may concern:

Be it known that I, W ALTER E. Emmi, a citizen of the United States,residing at Peoria, in the county of Peoria, State of Illinois, haveinvented a new and useful Time-Controlled Furnace-Starter; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in. the art towhich it appertains to make and use the same.

The present invention relates to a time controlled fire starting device,and has for its object to provide a device of this character whichembodies novel features of construction whereby the dampers of a furnacewhich have been previously set to check the fire can be automaticallyreleased and shifted in their positions to start the fire and cause itto burn.

Further objects of the invention are to provide a time controlledfurnace starter which is comparatively simple and inexpensive in itsconstruction, which can be readily ttached to any conventionalconstruction of stove or furnace, which is dependable in its operation,and which will enable a previously banked furnace fire to beautomatically started at a predetermined time in the morning so as toheat the house before the time for rising.

lVith these and other objects in view, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, the novel features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing descrip ion and accompanying drawings, in which Figure 1 is aside elevation of a conventional form of furnace having the fire starterapplied thereto.

Fig. 2 is a detail perspective view of the trip means for controllingthe fire starter.

Figs. 3 and 1 are detail views of a special form of trip mechanismconstructed for actuation by an ordinary clockwork to release the tripfinger at a predetermined time.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

furnace A, the numeral 1 designating the door for controlling the directdraft through the ash pit, and 2 the door for controlling the check orcold air draft in the smoke pipe 7 3. The mechanism may be supported inany suitable manner, although in the present 1nstance a platform or basei is shown as arranged upon the furnace A. A substantially horizontallydisposed cable extends over the platform 1, the ends thereof beingcarried downwardly around suitable guide pulleys 6 and operativelvconnected to the direct draft 1 and check draft 2, respectively. Theguide pulleys 6 are shown as carried by bracket arms 7 projecting fromthe platform 4-, and the cable 5 is of such a length that when the checkdraft 2 is closed the direct draft 1 is open, and vice versa. Ifnecessary, suitable means such as the weight 8 upon the cable 5 may beprovided for normally moving the cable to close the check draft 2 andopen the direct draft 1. this being the adjust ment which is requiredfor starting the fir An intermediate portion of the horizontallydisposed cable 5 is engaged by a vertically disposed trip lever 9, saidlever bein longitudinally slotted at 10 to receive the cable and beingpivotally mounted at its upper end upon a standard 11 projecting fromthe platform 4. A knob or enlargement 12 in the cable 5 engages theslotted portion 10 of the lever to swing the lever (0 one side when thecable is released and per-- mit it to move into such a position as toclose the check draft 2 and open the direct draft 1. lhis position ofthe parts is indicated by Fig. 1.

The lower end of the trip lever 9 is arranged for engagement *ith' acomparatively short horizontally disposed trip arm 13 which is rigidwith a longer trip arm 14. In the present instance these two trip arms13 and 14 are formed from a single length of wire which is coiled at thejunction of the trip arms to provide an eye 15 which is pivoted upon thestandard 11, being confined against up and down movement thereon by thecollars 16. The short arm 13 projects into the path of the lower end ofthe vertically swinging trip lever 9, while the long arm 1% isdesignedto be engaged by the trip finger 17 of a clockwork or timecontrolled mechanism 18 which is suitably mounted upon the platform l.Referring to Figs. 3 and 4, the numeral 19 designates the frame of theclockwork mechanism, and 20 ashaft'which is provided atthe' rear endthereof with a finger piece 21 and at the forward endthereof with apointer 22 adapted to play over the numerals of a small dial in the samemanner as the small pointer of an ordinary alarm clock, and to be set atany desired position, according to the particular time when it may bedesired to release the trip mechanism. A pinion 23 is slidably mountedupon the shaft 20 and geared to the clockwork mechanism in the usualmanner so as to make one complete revolution every twelve hours. A boss24.- on the pinion 20 is notched or recessed at 25 to receive a finger26 on the shaft 20. This linger normally rides upon the edge of the boss25': and holds the pinion 25 against movement on the shaft 20, due tothe pressure of the resilient arm 27 a 'ainst the pinion, although whenthe pinion has been revolved by the clockwork mechanism to bring thenotch under the finger 26, the pinion is moved longitudinally upon theshaft by the spring 27, the laterally bent end 27 of the springsimultaneously clearing and becoming disengaged from a lateral arm 28 ona rock shaft 29. A second arm 30 on the rock shaft is engaged by aspring 3], so that as soon as the rock shaft is released it is rotated,tnereby swinging the trip finger 17 which is rigid therewith andprojects upwardly through the top of the clcck works, and disengagingthe said trip finger from the trip arm ll. The pull upon the cable 5,caused by the weight 8 will then move the cable and reverse the previousposition of the dampers, closing the check draft 2 and opening thedirect draft 1.

W hen using the device it will be obvious that upon retiring or fixingthe fire for the n ght, the device will be set to check the fire, thetrip lever 9 being engaged by the trip arm l3, and the trip arm l-lbeing engaged by the trip finger l? of the clock work mechanism, so asto hold the cable 5 against the action of the weight 8 with the checkdraft 2 open and the direct draft 1 closed. The shaft 20 of theclockworks will be rotated until the small pointer is positioned uponthe dial according to the time in the morning when it desired to startthe fire. The dampers will thus be held in position to check the fireuntil the proper time for start ing it, when the movement of the pinion23 will operate as previously described to release the trip iinger 17and permit the trip arms 13 and 1%, together with the vertical lever 9to be swung into inoperative positions as the cable 5 is moved by theaction of the weight 8 and the position of the dampers shifted to startthe fire. The house can thus be heated in the morning before the timefor rising, and the end of the cable 5 is detachably connected to thedirect draft door 1 by means of a hook 32 so that it can be disengagedtherefrom during the day, thereby enabling the furnace to be manipulatedand adjusted in the usual manner at all times except when the mechanismis set for an automatic starting of the fire at a predetermined time.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is v 1. A device of the character describedincluding a horizontally disposed and longitudinally movable cablehaving a stop thereon, means acting upon the cable for moving it in onedirection, a vertically disposed swinging lever pivoted at its upper endand having a slotted portion which loosely receives the cable and isengaged by the stop thereon, a horizontally swinging trip arm mounted toengage the lower end of the vertically disposed swinging lever and to(306perate therewith to hold the cable against movement, and a timecontrolled trip finger for releasing the trip arm at a predeterminedtime.

2. A. device of the character described, including a horizontallydisposed and longitudinally movable cable, means acting upon the cablefor moving it in one direction, a standard arranged adjacent to thecable, a vertically disposed swinging lever pivotally mounted upon thestandard at its upper end and engaging the cable at its lower end, ashort horizontal trip arm and a long trip arm connected at theirjunction by a coil which pivotally engages the standard, the short triparm being adapted to engage the vertical lever for cooperation therewithto hold the cable against movement, and a time controlled trip fingerfor engaging and automatically releasing the long trip arm at apredetermined time.

3. A. device of the character described, including a horizontallydisposed and longitudinally movable cable, means acting upon the cablefor moving it in one direction, a vertically disposed swinging leverengaging the cable, a horizontally disposed trio arm engaging thevertically disposed lever for cooperation therewith to hold the cableagainst movement, a second trip arm having a spaced and parallelrelation to the first mentioned trip arm and rigid therewith, and a timecontrolled trip finger for engaging the second trip arm and releasing itat a predetermined time.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

W'ALTER E. EMERY.
